What will it take for the Global Plan priority countries in Sub-Saharan Africa to eliminate mother-to-child transmission of HIV?

HIV Vulnerability Typologies Among Adolescent Girls and Young Women in Lesotho: A Population-Based, Cross-Sectional, Latent Class Analysis

ABSTRACT

Adolescent girls and young women ages 15-29 years (AGYW) living in Lesotho experience a disproportionate HIV burden. Using a household-based national survey in Lesotho, we conducted a three-step latent class analysis to identify typologies of AGYW most vulnerable to HIV infection. We first classified AGYW into HIV vulnerability groups based on self-reported sexual behaviors, then identified associations between typology and HIV diagnosis. HIV vulnerability behaviors included early sexual debut, condomless sex, multiple sexual partners in the past year, sex with partners they do not know the status of or are living with HIV, age disparate sex, use of contraceptives, and having children. Across all age groups, we found that HIV vulnerability typologies could be described as low vulnerability, high vulnerability, and parous. As AGYW age, they engage in more types of higher vulnerability sexual behaviors; interventions to reduce this risk should start at a younger age. Our findings emphasize the importance of implementing and scaling up biomedical strategies such as pre-exposure prophylaxis.

Global, regional, and national burden of HIV/AIDS, 1990-2021, and forecasts to 2050, for 204 countries and territories: the Global Burden of Disease Study 2021

BACKGROUND

As set out in Sustainable Development Goal 3.3, the target date for ending the HIV epidemic as a public health threat is 2030. Therefore, there is a crucial need to evaluate current epidemiological trends and monitor global progress towards HIV incidence and mortality reduction goals. In this analysis, we assess the current burden of HIV in 204 countries and territories and forecast HIV incidence, prevalence, and mortality up to 2050 to allow countries to plan for a sustained response with an increasing number of people living with HIV globally.

METHODS

We used the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 analytical framework to compute age-sex-specific HIV mortality, incidence, and prevalence estimates for 204 countries and territories (1990-2021). We aimed to analyse all available data sources, including data on the provision of HIV programmes reported to UNAIDS, published literature on mortality among people on antiretroviral therapy (ART) identified by a systematic review, household surveys, sentinel surveillance antenatal care clinic data, vital registration data, and country-level case report data. We calibrated a mechanistic simulation of HIV infection and natural history to available data to estimate HIV burden from 1990 to 2021 and generated forecasts to 2050 through projection of all simulation inputs into the future. Historical outcomes (1990-2021) were simulated at the 1000-draw level to support propagation of uncertainty and reporting of uncertainty intervals (UIs). Our approach to forecasting utilised the transmission rate as the basis for projection, along with new rate-of-change projections of ART coverage. Additionally, we introduced two new metrics to our reporting: prevalence of unsuppressed viraemia (PUV), which represents the proportion of the population without a suppressed level of HIV (viral load <1000 copies per mL), and period lifetime probability of HIV acquisition, which quantifies the hypothetical probability of acquiring HIV for a synthetic cohort, a simulated population that is aged from birth to death through the set of age-specific incidence rates of a given time period.

FINDINGS

Global new HIV infections decreased by 21·9% (95% UI 13·1-28·8) between 2010 and 2021, from 2·11 million (2·02-2·25) in 2010 to 1·65 million (1·48-1·82) in 2021. HIV-related deaths decreased by 39·7% (33·7-44·5), from 1·19 million (1·07-1·37) in 2010 to 718 000 (669 000-785 000) in 2021. The largest declines in both HIV incidence and mortality were in sub-Saharan Africa and south Asia. However, super-regions including central Europe, eastern Europe, and central Asia, and north Africa and the Middle East experienced increasing HIV incidence and mortality rates. The number of people living with HIV reached 40·0 million (38·0-42·4) in 2021, an increase from 29·5 million (28·1-31·0) in 2010. The lifetime probability of HIV acquisition remains highest in the sub-Saharan Africa super-region, where it declined from its 1995 peak of 21·8% (20·1-24·2) to 8·7% (7·5-10·7) in 2021. Four of the seven GBD super-regions had a lifetime probability of less than 1% in 2021. In 2021, sub-Saharan Africa had the highest PUV of 999·9 (857·4-1154·2) per 100 000 population, but this was a 64·5% (58·8-69·4) reduction in PUV from 2003 to 2021. In the same period, PUV increased in central Europe, eastern Europe, and central Asia by 116·1% (8·0-218·2). Our forecasts predict a continued global decline in HIV incidence and mortality, with the number of people living with HIV peaking at 44·4 million (40·7-49·8) by 2039, followed by a gradual decrease. In 2025, we projected 1·43 million (1·29-1·59) new HIV infections and 615 000 (567 000-680 000) HIV-related deaths, suggesting that the interim 2025 targets for reducing these figures are unlikely to be achieved. Furthermore, our forecasted results indicate that few countries will meet the 2030 target for reducing HIV incidence and HIV-related deaths by 90% from 2010 levels.

INTERPRETATION

Our forecasts indicate that continuation of current levels of HIV control are not likely to attain ambitious incidence and mortality reduction targets by 2030, and more than 40 million people globally will continue to require lifelong ART for decades into the future. The global community will need to show sustained and substantive efforts to make the progress needed to reach and sustain the end of AIDS as a public threat.

Rapid systematic review of interventions to improve antenatal screening rates for syphilis, hepatitis B, and HIV in low- and middle-income countries

BACKGROUND

Infectious diseases including syphilis, HIV, and hepatitis B are major contributors to maternal and neonatal morbidity and mortality worldwide, especially in low- and middle-income countries (LMICs). The World Health Organization has prioritized elimination of vertical transmission of these three diseases.

OBJECTIVES

To rapidly assess the impact of interventions designed to improve antenatal screening rates for syphilis, HIV, and hepatitis B in LMICs and to identify areas for future implementation research.

SEARCH STRATEGY

A comprehensive search was conducted across PubMed, Embase, and EconLit, targeting articles published between January 1, 2013, and June 27, 2023.

SELECTION CRITERIA

We included quantitative interventional studies in English, involving pregnant adults (15 years or older) from LMICs. Exclusions were studies based in high-income countries, qualitative studies, or those investigating accuracy of diagnostic methods.

DATA COLLECTION AND ANALYSIS

From an initial 5549 potential studies, 27 were finalized for review after various screening stages. Data extraction covered aspects such as study design, intervention details, and outcomes. Findings were qualitatively synthesized within a systems thinking framework.

MAIN RESULTS

The interventions assessed varied in terms of geographic locations, health care system levels, and modalities. The review highlighted the effectiveness of interventions such as community health interventions, service quality improvements, and financial incentives.

CONCLUSIONS

The study underscores the potential of specific interventions in enhancing antenatal screening rates in LMICs. However, there is a discernible research gap concerning hepatitis B. The findings emphasize the importance of capacity building and health systems strengthening in public health interventions.

Evaluation of Quality of Prevention of Mother to Child Transmission of HIV Service Provision and Its Determinants: The Case of Health Facility Readiness and Mothers' Perspectives

Background

Prevention of Mother-To-Child Transmission of HIV (PMTCT) is a comprehensive intervention aimed at reducing vertical transmission. More than 90% of pediatric AIDS cases are caused by MTCT. However, the quality of care has lagged in terms of service integration, client satisfaction, and facility readiness, although improvements have been observed. Evidence on the quality of PMTCT services is required by clinicians, and policymakers. Therefore, this study aimed to evaluate the effectiveness of PMTCT services provided by public health facilities in Northwest Ethiopia.

Methods

This cross-sectional study was conducted at nine public health facilities in Gondar city between June 1 and July 17, 2022. A total of 334 mothers were participated. The Structure-Process-Outcome components were used to evaluate service quality. About 135 counseling sessions were observed. The SPSS 26 software was used for statistical analyses. To identify mothers' satisfaction with the service, P-values < 0.25, and < 0.05 were considered in the binary and multiple logistic regression analyses to identify significant variables, respectively.

Results

The overall performance of the health facilities was 74.09% (72.19-76.01 CI 95%). In 88.89% of cases, the output quality was higher and rated as good. However, the quality of the input and process services was 60.40% and 72.97%, respectively. Women's satisfaction was 67.09%. Women aged 15-24 years (AOR= 0.31; 95% CI:0.06, 0.79), formally educated (AOR=0.59; 95% CI:0.35, 0.67), > one hour of arrival (AOR=0.71; 95% CI:0.55, 0.93), > 30 minutes waiting time (AOR=0.23; 95% CI:0.11, 0.37), sufficient time for counseling (AOR=2.83; 95% CI:1.72, 3.97), and opening hours (AOR=4.27; 95% CI:2.09, 6.67) were factors associated with satisfaction in women.

Conclusion

The quality of PMTCT service provision and mothers' satisfaction were low. Reducing waiting time, punctuality of service providers, adequate counselling, and availability of basic resources can boost mothers' satisfaction.

Temporal Trends and Determinants of HIV Testing at Antenatal Care in Sub-Saharan Africa: A Pooled Analysis of Population-Based Surveys (2005-2021)

BACKGROUND

In sub-Saharan Africa (SSA), integrating HIV testing into antenatal care (ANC) has been crucial toward reducing mother-to-child transmission of HIV. With the introduction of new testing modalities, we explored temporal trends in HIV testing within and outside of ANC and identified sociodemographic determinants of testing during ANC.

METHODS

We analyzed data from 139 nationally representative household surveys conducted between 2005 and 2021, including more than 2.2 million women aged 15-49 years in 41 SSA countries. We extracted data on women's recent HIV testing history (<24 months), by modality (ie, at ANC versus outside of ANC) and sociodemographic variables (ie, age, socioeconomic status, education level, number of births, urban/rural). We used Bayesian generalized linear mixed models to estimate HIV testing coverage and the proportion of those that tested as part of ANC.

RESULTS

HIV testing coverage (<24 months) increased substantially between 2005 and 2021 from 8% to 38%, with significant variations between countries and subregions. Two percent of women received an HIV test in the 24 months preceding the survey interview as part of ANC in 2005 and 11% in 2021. Among women who received an HIV test in the 24 months preceding the survey, the probability of testing at ANC was significantly greater for multiparous, adolescent girls, rural women, women in the poorest wealth quintile, and women in West and Central Africa.

CONCLUSION

ANC testing remains an important component to achieving high levels of HIV testing coverage and benefits otherwise underserved women, which could prove instrumental to progress toward universal knowledge of HIV status in SSA.

The effects of revised peer-counselor support on the PMTCT cascade of care: results from a cluster-randomized trial in Kenya (the EMMA study)

BACKGROUND

This study evaluated the effect of revisions to existing peer-counselor services, called Mentor Mothers (MM), at maternal and child health clinics on medication adherence for women living with HIV (WLWH) in Kenya and on early infant HIV testing.

METHODS

The Enhanced Mentor Mother Program study was a 12-site, two-arm cluster-randomized trial enrolling pregnant WLWH from March 2017 to June 2018 (with data collection through September 2020). Six clinics were randomized to continued MM-supported standard care (SC). Six clinics were randomized to the intervention arm (INT = SC plus revised MM services to include more one-on-one interactions). Primary outcomes for mothers were defined as: (PO1) the proportion of days covered (PDC) with antiretroviral therapy (ART) ≥ 0.90 during the last 24-weeks of pregnancy; and (PO2) ≥ 0.90 PDC during the first 24-weeks postpartum. Secondary outcomes were infant HIV testing according to national guidelines (at 6, 24, and 48 weeks). Crude and adjusted risk differences between study arms are reported.

RESULTS

We enrolled 363 pregnant WLHV. After excluding known transfers and subjects with incomplete data extraction, data were analyzed for 309 WLWH (151 SC, 158 INT). A small share achieved high PDC during the prenatal and postnatal periods (0.33 SC/0.24 INT achieved PO1; 0.30 SC/0.31 INT achieved PO2; crude or adjusted risk differences were not statistically significant). In addition, ~ 75% in both study arms completed viral load testing during year two after enrollment, with > 90% suppressed in both arms. For infants, ≥ 90% in both arms had at least one HIV test through study follow up (76 weeks) but testing on schedule according to PMTCT guidelines was uncommon.

CONCLUSIONS

While national guidelines in Kenya recommended that all HIV-infected pregnant women take a daily antiretroviral regimen for life following a HIV diagnosis, results presented here indicate that a minor share achieved high medication coverage during the prenatal and postnatal periods analyzed. In addition, adjustments to Mentor-Mother services showed no improvement in study outcomes. The lack of effect for this behavioral intervention is relatively consistent with the existing literature to improve mother-infant outcomes along the PMTCT care cascade.

Uptake of prevention of mother-to-child transmission cascade services in Burkina Faso between 2013 and 2020: are we on the right track?

BACKGROUND

The use of services to prevent mother-to-child transmission (PMTCT) of the human immunodeficiency virus (HIV) remains a serious challenge in sub-Saharan Africa. In the last decade, Burkina Faso has implemented numerous policies to increase the use of PMTCT services by pregnant women and their partners, as well as children. This study assesses trends in the uptake of PMTCT services in Burkina Faso from 2013 to 2020 in order to study the progress and gaps in achieving the national and international targets set for 2020.

METHODS

A repeated cross-sectional analysis was performed using data extracted from district health information software version 2. Percentages were computed for each PMTCT indicator and comparisons between the years were made using a chi-square test for trends with a significance threshold of 5%. Regions were not compared with each other.

RESULTS

The proportion of pregnant women who were tested and received their results significantly increased from 47.9% in 2013 to 84.6% in 2020 (p value < 0.001). Of the 13 regions in the country, only 1 region met the 95% national targets whereas, 6 regions met the 90% international targets for this indicator. The proportions of HIV-positive women receiving antiretroviral therapy (ART) increased from 90.8% in 2013 to 100% in 2020. In the same period, the proportion of exposed infants who received antiretroviral prophylaxis increased from 64.3% in 2013 to 86.8% in 2020. Only 3 regions reached the national and international targets for this indicator. A positive trend was also observed for the indicator related to screening at 2 months or later of exposed infants using Polymerase Chain Reaction (PCR) technic; with the rate rising from 7.4% in 2013 to 75.7% in 2020. However, for this indicator, the national and international targets were not achieved considering the national and regional settings. Concerning the women's partners, the proportion of those who tested for HIV increased from 0.9% in 2013 to 4.5% in 2020, with only 1 region that fully met the national target of 10% in 2020. The prevalence of HIV in this particular group was 0.5% in 2020.

CONCLUSIONS

PMTCT indicators show an increase from 2013 to 2020 but with a strong disparity between regions. National and international targets have not been achieved for any indicator; except for those related to women receiving ART. Strengthening strategies to effectively engage women and their partners on the use of PMTCT cascade services could help reduce mother-to-child transmission in Burkina Faso.

The mother-to-child transmission of HIV-1 and profile of viral reservoirs in pediatric population: A systematic review with meta-analysis of the Cameroonian studies

BACKGROUND

The mother-to-child transmission of HIV-1 (MTCT) remains on the major route of HIV-transmission among pediatric populations in Africa. Though a prevention of MTCT (PMTCT) high-priority country, data on the MTCT burdens in Cameroon remains fragmented.

OBJECTIVE

We sought to assess the pooled MTCT rate, its risk-factors, and to characterize viral reservoirs of infected-children in Cameroon.

METHODS

All relevant observational cohort and cross-sectional studies conducted in Cameroon were searched from PubMed, African Journals Online, Google scholar, ScienceDirect and academic medical education databases. Heterogeneity and publication bias were respectively assessed by the I2 statistic and the Egger/funnel plot test. Meta-analysis was performed using the random effects model. MTCT rate >5% was considered as "high". This review was registered in the Prospero database, CRD42021224497.

RESULTS

We included a total of 29 studies and analyzed 46 684 children born from HIV-positive mothers. The overall rate of MTCT was 7.00% (95% CI = 6.07-8.51). According to regions, the highest burden was in Adamaoua-region (17.51% [95% CI:14.21-21.07]) with only one study found. PMTCT option-B+ resulted in about 25% reduction of MTCT (8.97% [95% CI: 8.71-9.24] without option-B+ versus 2.88% [95% CI: 5.03-9.34] with option-B+). Regarding risk-factors, MTCT was significantly associated with the absence of PMTCT-interventions both in children (OR:5.40 [95% CI: 2.58-11.27]) and mothers (OR: 3.59 [95% CI: 2.15-5.99]). Regarding viral reservoirs, a pro-viral DNA mean of 3.34±1.05 log10/mL was observed among 5/57 children and archived HIV drug resistance mutations were identified in pro-viral DNA marker among 21/79 infected-children.

CONCLUSION

In spite of the dropdown in MTCT following option-B+ implementation, MTCT remains high in Cameroon, with substantial disparities across regions. Thus, in this era of option-B+, achieving MTCT elimination requires interventions in northern-Cameroon. The variation in pro-viral load in infected-children underlines the relevance of characterizing viral reservoirs for possible infection control in tropical settings.

Maternal and health care workers' perspectives on exclusive breastfeeding in the context of maternal HIV infection, in Busia county, western Kenya: a mixed methods cross-sectional survey

BACKGROUND

World Health Organization recommends exclusive breastfeeding (EBF) for 6 months with maternal active antiretroviral therapy (ART) to prevent mother-to-child transmission (PMTCT) of HIV. However, EBF in low resource settings remains low. We explored perspectives of EBF by HIV-infected mothers and health care workers in Busia County with a high prevalence of HIV to understand factors influencing the practice.

METHODS

A mixed methods cross-sectional survey using concurrent quantitative and qualitative data collection methods was conducted at PMTCT clinics. Data on socio-demography, young infant feeding practices, maternal and infant health was collected between February 2013 and August 2015 from 371 purposively sampled HIV-infected mother-infant dyads using a semi-structured questionnaire. Focus group discussions with mothers, in-depth interviews and passive observation of health care workers during interaction with mothers were conducted. Significance of difference between mothers practicing EBF or not was tested by Chi-square and Fisher's exact tests setting significance level at 5%. Qualitative data was coded and content analyzed to generate themes.

RESULTS

Three hundred and forty-nine (94%) mothers practiced EBF. Maternal comprehension of EBF to PMTCT of HIV influenced choice and practice of EBF (P value = 0.019 and < 0.001 respectively). Health care workers emphasized adherence to ART and offered nutritional supplementation during EBF. Health care workers' nutritional counseling in the context of maternal HIV was poor. Mentor mothers shared their experiences with mothers and offered live case demonstrations of their successfully EBF, healthy and HIV-uninfected children. The main threats to EBF were teenage motherhood, low maternal education and working during EBF.

CONCLUSIONS

EBF among HIV-infected mothers in Busia County, Kenya was high. Health education and counselling by health care workers, maternal comprehension of ART adherence to PMTCT of HIV, nutritional supplementation and mentor mothers' peer counseling using live case demonstrations of HIV-uninfected EBF children promoted and sustained practice of EBF for 6 months. Teenage motherhood, low maternal education and having to work threatened EBF.

Eliminating HIV transmission through breast milk from women taking antiretroviral drugs

Ameena Goga and colleagues argue that frequent testing of maternal viral load is needed to eliminate HIV transmission through breast milk in low and middle income settings

Incidence and disability-adjusted life years of maternal disorders at the global, regional, and national levels from 2007 to 2017: A systematic analysis for the Global Burden of Disease Study 2017

OBJECTIVE

To report the global burden of maternal disorders and their main subcategories in 195 countries and territories between 2007 and 2017.

METHODS

The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 estimated maternal disease burden at global, regional, and country levels. Maternal disorders were disaggregated into 10 categories, and estimated incidence and disability-adjusted life years (DALYs) of maternal disorders were reported separately. Indicators were estimated in different geographic settings and different sociodemographic index (SDI) regions. Based on GBD 2017 estimates, we systematically examined the incidence and DALYs of maternal disorders and their main subcategories at the global, regional, and national levels during the period from 2007 to 2017 by age and SDI.

RESULTS

Globally, a total of 7.98 million maternal disorders occurred in 2017, with a 4.33% (95% uncertainty interval [UI] 3.24%-5.60%) decrease in age-standardized incidence rate and a more significant decrease (30.26%) in the age-standardized rate of DALYs. Most incidences and DALYs were found in low-income and middle-income countries, especially in the sub-Saharan region. The greatest incidence of maternal disorders was found to be in maternal abortion and miscarriage (2.00 million), and the highest disease burden was in maternal hemorrhage (2.23 million).

CONCLUSION

A slight increase in the incidence of maternal disorders and substantial reductions in DALYs of overall maternal disorders and their main subcategories were found from 2007 to 2017, especially in low-income countries and the sub-Saharan region. Maternal hemorrhage, hypertensive disorders, and indirect maternal death were the top three causes of maternal disorders disease burden.

Experiences and Reasons of Attrition from Option B+ Among Mothers Under Prevention of Mother to Child Transmission Program in Northwest Ethiopia: Qualitative Study

Background

Human immunodeficiency virus-infected children share the highest risk of death compared with all other age groups, and more than 90% of this viral infection of children was accounted for by transmission from mother to infant. This rate can be prevented and reduced with implementation of option B+ effectively. However, unacceptably high lost follow-up of mothers highly affected the effectiveness of this program. In Ethiopia, only 71% of mothers were adherent on their follow-up. So, this study was aimed to understand the reasons and experiences of lost follow-up of mothers under the prevention of mother to child transmission (option B+) program in North West Ethiopia.

Methods

A qualitative study using a case study design was carried out using in-depth interviews among 20 mothers who had started the option B+ treatment protocol but discontinued their follow-up for more than two months, and 6 key informants and individuals who were engaged in management and control of human immunodeficiency virus at Woreda and Zonal level. An unstructured interview guide was used and translated into the local language. Study participants were selected using purposive sampling technique. After written consent was obtained, all study participants’ interviews were audio-recorded and analyzed using deductive content analysis.

Results

A total of 26 mothers participated in this study. Accordingly, the most frequently raised reasons were lack of formal education which affects income level, lack of disclosure, lack of partner and family support, absence of male involvement and stigma-discrimination. But, unavailability of option B+ regimens in the nearest health facility or long distance from health facility, discordance and lack of experienced professionals in terms of counseling during initiation were also essential reasons.

Conclusion

Educational and economic empowerment intervention (particularly for vulnerable households), promoting family support and male involvement, active counseling at initiation and during follow up and community level awareness improvement should be addressed to increase option B+ regimen adherence and retention.

Community-based progress indicators for prevention of mother-to-child transmission and mortality rates in HIV-exposed children in rural Mozambique

Background

Eliminating mother-to-child HIV-transmission (EMTCT) implies a case rate target of new pediatric HIV-infections< 50/100,000 live-births and a transmission rate < 5%. We assessed these indicators at community-level in Mozambique, where MTCT is the second highest globally..

Methods

A cross-sectional household survey was conducted within the Manhiça Health Demographic Surveillance System in Mozambique (October 2017–April 2018). Live births in the previous 4 years were randomly selected, and mother/child HIV-status was ascertained through documentation or age-appropriate testing. Estimates on prevalence and transmission were adjusted by multiple imputation chained equation (MICE) for participants with missing HIV-status. Retrospective cumulative mortality rate and risk factors were estimate by Fine-Gray model.

Results

Among 5000 selected mother-child pairs, 3486 consented participate. Community HIV-prevalence estimate in mothers after MICE adjustment was 37.6% (95%CI:35.8–39.4%). Estimates doubled in adolescents aged < 19 years (from 8.0 to 19.1%) and increased 1.5-times in mothers aged < 25 years. Overall adjusted vertical HIV-transmission at the time of the study were 4.4% (95% CI:3.1–5.7%) in HIV-exposed children (HEC). Pediatric case rate-infection was estimated at 1654/100,000 live-births. Testing coverage in HEC was close to 96.0%; however, only 69.1% of them were tested early(< 2 months of age). Cumulative child mortality rate was 41.6/1000 live-births. HIV-positive status and later birth order were significantly associated with death. Neonatal complications, HIV and pneumonia were main pediatric causes of death.

Conclusions

In Mozambique, SPECTRUM modeling estimated 15% MTCT, higher than our district-level community-based estimates of MTCT among HIV-exposed children. Community-based subnational assessments of progress towards EMTCT are needed to complement clinic-based and modeling estimates.

Uganda's "EID Systems Strengthening" model produces significant gains in testing, linkage, and retention of HIV-exposed and infected infants: An impact evaluation

Introduction

A review of Uganda’s HIV Early Infant Diagnosis (EID) program in 2010 revealed poor retention outcomes for HIV-exposed infants (HEI) after testing. The review informed development of the ‘EID Systems Strengthening’ model: a set of integrated initiatives at health facilities to improve testing, retention, and clinical care of HIV-exposed and infected infants. The program model was piloted at several facilities and later scaled countrywide. This mixed-methods study evaluates the program’s impact and assesses its implementation.

Methods

We conducted a retrospective cohort study at 12 health facilities in Uganda, comprising all HEI tested by DNA PCR from June 2011 to May 2014 (n = 707). Cohort data were collected manually at the health facilities and analyzed. To assess impact, retention outcomes were statistically compared to the baseline study’s cohort outcomes. We conducted a cross-sectional qualitative assessment of program implementation through 1) structured clinic observation and 2) key informant interviews with health workers, district officials, NGO technical managers, and EID trainers (n = 51).

Results

The evaluation cohort comprised 707 HEI (67 HIV+). The baseline study cohort contained 1268 HEI (244 HIV+). Among infants testing HIV+, retention in care at an ART clinic increased from 23% (57/244) to 66% (44/67) (p < .0001). Initiation of HIV+ infants on ART increased from 36% (27/75) to 92% (46/50) (p < .0001). HEI receiving 1st PCR results increased from 57% (718/1268) to 73% (518/707) (p < .0001). Among breastfeeding HEI with negative 1st PCR, 55% (192/352) received a confirmatory PCR test, a substantial increase from baseline period. Testing coverage improved significantly: HIV+ pregnant women who brought their infants for testing after birth increased from 18% (67/367) to 52% (175/334) (p < .0001). HEI were tested younger: mean age at DBS test decreased from 6.96 to 4.21 months (p < .0001). Clinical care for HEI was provided more consistently. Implementation fidelity was strong for most program components. The strongest contributory interventions were establishment of ‘EID Care Points’, integration of clinical care, longitudinal patient tracking, and regular health worker mentorship. Gaps included limited follow up of lost infants, inconsistent buy-in/ownership of health facility management, and challenges sustaining health worker motivation.

Discussion

Uganda’s ‘EID Systems Strengthening’ model has produced significant gains in testing and retention of HEI and HIV+ infants, yet the country still faces major challenges. The 3 core concepts of Uganda’s model are applicable to any country: establish a central service point for HEI, equip it to provide high-quality care and tracking, and develop systems to link HEI to the service point. Uganda’s experience has shown the importance of intensively targeting systemic bottlenecks to HEI retention at facility level, a necessary complement to deploying rapidly scalable technologies and other higher-level initiatives.

Impact of breastfeeding, maternal antiretroviral treatment and health service factors on 18-month vertical transmission of HIV and HIV-free survival: results from a nationally representative HIV-exposed infant cohort, South Africa

BACKGROUND

We analysed the impact of breastfeeding, antiretroviral drugs and health service factors on cumulative (6 weeks to 18 months) vertical transmission of HIV (MTCT) and 'MTCT-or-death', in South Africa, and compared estimates with global impact criteria to validate MTCT elimination: (1) <5% final MTCT and (2) case rate ≤50 (new paediatric HIV infections/100 000 live births).

METHODS

9120 infants aged 6 weeks were enrolled in a nationally representative survey. Of 2811 HIV-exposed uninfected infants (HEU), 2644 enrolled into follow-up (at 3, 6, 9, 12, 15 and 18 months). Using Kaplan-Meier analysis and weighted survey domain-based Cox proportional hazards models, we estimated cumulative risk of MTCT and 'MTCT or death' and risk factors for time-to-event outcomes, adjusting for study design and loss-to-follow-up.

RESULTS

Cumulative (final) MTCT was 4.3% (95% CI 3.7% to 5.0%); case rate was 1290. Postnatal MTCT (>6 weeks to 18 months) was 1.7% (95% CI 1.2% to 2.4%). Cumulative 'MTCT-or-death' was 6.3% (95% CI 5.5% to 7.3%); 81% and 62% of cumulative MTCT and 'MTCT-or-death', respectively, occurred by 6 months. Postnatal MTCT increased with unknown maternal CD4-cell-count (adjusted HR (aHR 2.66 (1.5-5.6)), undocumented maternal HIV status (aHR 2.21 (1.0-4.7)) and exclusive (aHR 2.3 (1.0-5.2)) or mixed (aHR 3.7 (1.2-11.4)) breastfeeding. Cumulative 'MTCT-or death' increased in households with 'no refrigerator' (aHR 1.7 (1.1-2.9)) and decreased if infants used nevirapine at 6 weeks (aHR 0.4 (0.2-0.9)).

CONCLUSIONS

While the <5% final MTCT target was met, the case rate was 25-times above target. Systems are needed in the first 6 months post-delivery to optimise HEU health and fast-track ART initiation in newly diagnosed mothers.

Integrating the prevention of mother-to-child transmission of HIV into primary healthcare services after AIDS denialism in South Africa: perspectives of experts and health care workers - a qualitative study

Background

Integrating Prevention of Mother-to-Child Transmission (PMTCT) programmes into routine health services under complex socio-political and health system conditions is a priority and a challenge. The successful rollout of PMTCT in sub-Saharan Africa has decreased Human Immunodeficiency Virus (HIV), reduced child mortality and improved maternal health. In South Africa, PMTCT is now integrated into existing primary health care (PHC) services and this experience could serve as a relevant example for integrating other programmes into comprehensive primary care. This study explored the perspectives of both experts or key informants and frontline health workers (FHCWs) in South Africa on PMTCT integration into PHC in the context of post-AIDS denialism using a Complex Adaptive Systems framework.

Methods

A total of 20 in-depth semi-structured interviews were conducted; 10 with experts including national and international health systems and HIV/PMTCT policy makers and researchers, and 10 FHCWs including clinic managers, nurses and midwives. All interviews were conducted in person, audio-recorded and transcribed. Three investigators collaborated in coding transcripts and used an iterative approach for thematic analysis.

Results

Experts and FHCWs agreed on the importance of integrated PMTCT services. Experts reported a slow and partial integration of PMTCT programmes into PHC following its initial rollout as a stand-alone programme in the aftermath of the AIDS denialism period. Experts and FHCWs diverged on the challenges associated with integration of PMTCT. Experts highlighted bureaucracy, HIV stigma and discrimination and a shortage of training for staff as major barriers to PMTCT integration. In comparison, FHCWs emphasized high workloads, staff turnover and infrastructural issues (e.g., lack of rooms, small spaces) as their main challenges to integration. Both experts and FHCWs suggested that working with community health workers, particularly in the post-partum period, helped to address cases of loss to follow-up of women and their babies and to improve linkages to polymerase-chain reaction (PCR) testing and immunisation.

Conclusions

Despite organised efforts in South Africa, experts and FHCWs reported multiple barriers for the full integration of PMTCT in PHC, especially postpartum. The results suggest opportunities to address operational challenges towards more integrated PMTCT and other health services in order to improve maternal and child health.
